Actor Seo Kang-joon and actress Lee Sung-kyung will appear as brother and sister in the much-anticipated TV drama “Cheese in the Trap.”Seo will take the role of Baik In-ho, a tough guy who has a soft spot for female protagonist Hong-seol, played by Kim Go-eun. Lee will play In-ho’s pretty yet obnoxious older sister Baik In-ha. In-ha uses her charm and beauty to attract as many guys as possible.

In the released photo by the producer tvN on Friday, both Seo and Lee boast their height and matching brown hair, brown eyes and porcelain face, coming off as real siblings. “Cheese in the Trap,” based on the webtoon of the same name, also stars actor Park Hae-jin as the male lead Yoo Jung.
